Cloud Run 中的视频上传 Flask 应用程序正在提供 没有此类文件或目录

Question

I am having a web application running locally on my laptop. Below is the python code snippet that takes the video from the HTML and uploads it to Cloud Storage:

@app.route('/' , methods=['POST', 'GET'])
def index():
    if request.method == 'POST':
        video = request.form['video']
        video2 = request.form['video2']
        
        if not video:
            flash('please upload your answer first')
        if not video2:
            flash('please upload your answer first')
        else:
            #store video to GCS
            video_list = [video,video2]
            for i in range(len(video_list)):
                upload_video_to_gcs(video_list[i],i)

def upload_video_to_gcs(video,video_num):
    # Setting credentials using the downloaded JSON file
    client = storage.Client.from_service_account_json(json_credentials_path='sa-credentials.json')
    # Creating bucket object
    bucket = client.get_bucket('bucket_name')
    # Name of the destination file in the bucket
    gcs_file_name = "".join(("video","_",str(video_num)))
    object_name_in_gcs_bucket = bucket.blob(gcs_file_name)
    object_name_in_gcs_bucket.upload_from_filename(video)
    return 1

It is working fine when running it locally on my laptop, in which the video is located in the same folder as the python file. However, when I deployed this web application on GCP Cloud Run(the video is no more existing in the same folder of the python file), I am getting the below error:

FileNotFoundError: [Errno 2] No such file or directory: 'sample_video.mp4'

Do you have any idea how to upload the video(existing anywhere on my laptop) through the web service hosted on Cloud Run on GCP.

Answer 1

The Python FileNotFoundError: [Errno 2] No such file or directory error is often raised by the os library. This error tells you that you are trying to access a file or folder that does not exist. To fix this error, check that you are referring to the right file or folder in your program.

Here is a similar case that was fixed by providing the correct path.
